Following the move by Audio Technica, Pionner Japan has released a portable headphone with a built in cord winding mechanism. Pretty soon every manufacturer will have a portable headphone model with a self winding cord mechanism. “Why didn’t I think of that before?” Of course, some people are asking, why not skip the cord altogether and go wireless?

The SE-MJ51R headphones are of closed design, with a 40mm dynamic driver utilizing “rare earth magnets”, with a frequency response from 8Hz to 25kHz, with a 105dB SPL output level, and a 32 Ohms impedance. It comes with four color schemes, black, blue, red, and white. What’s interesting is the use of a Memory Foam pads that will provide better noise sealing once it follows the shape of your ears. Oh, and it also comes with a “Bass Tune” feature. Awesome.
